silicone baby cup!What is the reason for the poor sealing effect of the silicone ring?

　　The aging life ability is the hard injury of the silicone ring. All silicone products suitable for sealing have such a defect. For example, our common mechanical doors and windows, electronic product sealing and automobile waterproof sealing rings will have certain defects. Silicone or rubber and other materials will gradually lose their functionality after being devastated by the environment and the test of time.

　　There are many main reasons for affecting the service life, but in any seal, the silicone ring will be affected by several common phenomena.

　　Affected by the size of the force or permanent compression, it can be installed according to the installation method, plane, concave-convex groove or groove, etc. The installation method of each product is different, which may lead to uneven force, center of force offset, and side weight. On the other hand, the compression and permanent deformation will be caused by the long-term backlog of stress. When the sealing silicone ring is removed again, it is likely that the deformation has occurred. Therefore, it is necessary to control the balance and the degree of stress during installation.

　　The wrong size of the product leads to the deformation of the gap:

　　The gap problem can be divided into several factors. First, because of the material's rubber problem, many silicone materials have poor resilience due to the formula, and the problem of insufficient tensile force leads to the leakage of the gap due to the weak force during use. Processing problems of silicone rings: For example, the product is brittle, which leads to the thin edge thickness of silicone products. This problem is prone to occur. If the product is soft, the rubber material has inner bulges and is not cooked. After long-term stretching and compression, there will be gaps in deformation. question.

　　The product becomes soft or brittle, which leads to functional failure. In many cases, it is not the structural problem of the material and the product, but the quality standard of the product is affected during the production and processing of the silicone rubber product manufacturer. For example, the hardness and softness of the product are not known during processing. It is required that if the processing time is prolonged, the product is too brittle and cracks appear during the installation process, or if the processing efficiency is to be improved, the product becomes soft, resulting in deformation of the product when it is stressed.

　　The hardness and softness are affected. In many cases, the function and structure of the product can be completely changed according to the different softness of the silicone rubber products. Therefore, the silicone sealing ring is subjected to stress, stretching, extrusion due to the selection of different hardness and softness during the use process. The appearance of pressure and other phenomena, the sealing ring will have some unavoidable problems, such as extrusion gap, excessive force, too high hardness, product deformation without rebound and other factors.
